The young leave the nest after 12 to 15 days and may be fed by the male for about two more weeks, while the female starts a second clutch. The female then joins the male in bringing food to the young. The male house finch typically has a red head, breast, and rump, but does not have red coloring on its brown back or wings. The female broods the young for the first few days after they hatch, and the male continues to bring food. Adult males have a rose red head, back and rump. Pairs breed in arid thorn scrub, but in the non-breeding. The female incubates 4 to 5 eggs for 13 to 14 days while the male brings her food. Adults have a long forked black tail, black wings with white wing bars and a large bill. The head and throat of the male are characteristically red, while the female is uniform gray-brown.

House Finches have longer tails and appear more slender overall, and also have slightly curved bills, in contrast to the straight bills found in the other two species. They lack clear white stripes on their heads. The breast streaks do not converge in a central spot as on many sparrows. Female House Finches have blurrier streaks and grayer undersides than the other two species. This helps to differentiate it from the other two. The House Finch, the most common and widespread of the three, typically has a red head, breast, and rump, but does not have red coloring on its brown back or wings. All three species are streaked, and the males of all three have red plumage.
